If you haven't done the tutorials yet, doing those can be a good idea.
Otherwise you can make something like this, its not a game:
You have to make each circle from 1 to 4 go to the square of the same color.
1. They cant touch the gray box in the middle.
2. Only 1 circle must move at the time.
3. The circles have to go there, not just "Teleport" there.
If you can do that, you will be well on your way. As this involve a lot of parts that you would need to make pretty much any type of game.
